Modulating the Swelling Behavior of Polymer Brushes via Interfacial Chemistry

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Modulating substrate surface chemistry of surface‐grafted polymer brushes via variation of the chemical composition of spacers that anchor initiators for surface‐initiated atom transfer polymerizations allows to tune swelling of these thin polymer films.

Silicon Nanoparticles and Methyl Jasmonate Enhance Productivity and Nutritional Quality of Vegetable Cluster Bean (Cyamopsis tetragonoloba L.) Under Deficit Irrigation

Plant Direct, Volume 10, Issue 8, August 2026.
ABSTRACT Cluster bean (Cyamopsis tetragonoloba L.) is usually grown for its high galactomannan content as an industrial crop. Young edible cluster bean pods are also eaten as a nutritious vegetable in many areas. There is little research on the effects of drought on pod yield or the nutritional content of edible cluster bean pods, even with the growing

Assessing GNSS Reflectometry for High‐Latitude 3D Ionospheric Imaging

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract This study investigates whether Global Navigation Satellite System Reflectometry (GNSS‐R) measurements from low‐Earth‐orbit (LEO) satellites can improve three‐dimensional (3D) ionospheric electron density imaging, with a focus on high‐latitude regions. Conventional ionospheric tomography is limited by sparse ground‐based receiver coverage over

Orbital reflectometry

, 2010
The occupation of d-orbitals controls the magnitude and anisotropy of the inter-atomic electron transfer in transition metal oxides and hence exerts a key influence on their chemical bonding and physical properties. Atomic-scale modulations of the orbital occupation at surfaces and interfaces are believed to be responsible for massive variations of the

Microsecond X‐ray reflectometry

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1112-1120, August 2026.
X‐ray reflectometry is accelerated to 213 µs net exposure time using galvanometer scanning, which enables unprecedented temporal resolution for studying dynamic thin‐film processes.We accelerate synchrotron X‐ray reflectometry (XRR) by more than an order of magnitude and demonstrate the acquisition of full reflectivity curves within 213 µs over a qz ...

Improving polarized neutron reflectometry experiments on soft‐matter samples: optimization of the solid substrate structure

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1192-1199, August 2026.
We demonstrate a Fisher‐information‐based strategy for optimizing the solid substrate structure in polarized neutron reflectometry experiments on soft‐matter samples. The approach identifies magnetic reference layer designs that improve experimentally accessible information and provides a general framework for more efficient reflectometry experiment ...

Grazing‐incidence scattering surveyed: towards reference methods for alignment and calibration

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1247-1253, August 2026.
With the recent gain in popularity of grazing‐incidence instruments, harmonization is needed to establish intercomparability. This review of existing instruments and methods highlights the diversity of approaches in the community and is a first step towards reference methods.Grazing‐incidence small‐angle scattering (GISAS) is a relatively young ...

A neutron microscope using a nested Wolter‐I condenser and a bank of diffractive–refractive achromatic objectives

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1282-1293, August 2026.
A neutron microscope is presented comprising a Wolter‐I nested mirror optic as condenser and a 2D array of neutron achromats as objective.We present a nested Wolter‐I mirror design for a neutron condenser, which is based on established X‐ray telescope technology.

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

New Phytologist, Volume 251, Issue 3, Page 1101-1115, August 2026.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.
